SPECIFICATION forming part of Letters Patent No. 725,175, dated April14, 1903.

' Application iled February 17, 1903l Serial No. 143,805. (No model.)

T0 @ZZ whom, it may concern.-

Be it known that I, JEAN A. THoRsnLL, a citizen of the United States,residing at Pittsburg, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inBolsters for Railway- Oars; and I do hereby declare the following to bea full, clear, and eXact description of the invention, such as willenable others skilled in the art to which it appertains to make andnsethe same.

My invention relates to railway-cars, has especial reference to holstersmade of structural or commercial steel or iron, and has for its objectstrengthl and durability with a reduction iu weight as compared withbolsters of this type in use; and the invention consists, primarily, inthe use of a single web as the main member or body of the bolster, aswill be fully disclosed in the following specication and claims.

In the accompanyingdrawings, which form part of this specification,Figure 1 represents a top plan View, partly in section, of my invention;Fig. 2, a side elevation of the same; Fig. 3, an inverted plan View withthe center plate and the side bearings removed; Fig. 4, a verticaltransverse section on lines 4 4, Figs. l and 2; Fig. 5, a like view onlines 5 5 on the same figures; Fig. 6, a top plan view and a sideelevation of the web. or body detached; Fig. 7, a like view of one ofthe angleplates on the top or upper side of the bolster; Fig. S, a likeview of one of the angleplates on the bottom or lower side of thebolster; Fig. 9, a like view of the top plate of the bolster; Fig. l0, atop plan view of a modified construction of the web, and Fig. 11 a likeview of another modified form of the web.

Reference being had to the drawings and the designating characters'thereon, 1 indicates the web or body of the bolster, provided with alateral bend, bulge, or swell 2 on each side thereof, which forms areinforce or brace for the web and the walls of a passage or chamber 3for a king-bolt. (Not shown.) The web may be made of two members, asshown in Fig. 6, in which the adjacent ends of the four members, asshown in Fig. 10, in which there are two members 1 and two short membershaving the lateral bend, bulge, or swell 2 to form the passage 3 andflanges 4, or it may be made of one continuous member 1 having thelateral bend, bulge, or swell 2 and a short piece having the lateralbend 2 to form the passage 3 and flanges 4 4, by which this short orsupplemental member is secured to the main member 1, as shown in Fig.11. In all of these constructions the web is made of a fiat bar ofmerchant metal, preferably steel, is deeper inV the center than at itsends, as shown in Figs. 2 and 6, is parallel in width from itslongitudinal center to a point in proximity to the outer edges of centerbearingplate 5, as indicated at 6 6, and inelines upward on each side ofthe center on its lower edge to about the p oints indicated by 7 7, fromwhich points the web is parallel to its ends, as indicated by S 8, andthe upper edge of the web is straight, thus forming a canltalver.

To each side of the web 1 and at the upper edge thereof is connected byrivets a laterally-extending plate 9 of angle-iron, bent laterally at lOto t around the lateral bend, bulge, or swell 2 in the web 1, and toeach side'ot' the web, at the lower or bottom edge, is secured in likemanner a laterally-extending plate-11 of angle-iron, bent laterally at12 to tit around the bulge 2 in the web, and these plates are bent inthe opposite direction to conform to the contour of the bottom edge ofthe web, as shown at 13, 14, and 15 in Fig. S.

The web 1 is provided with holes 16 16 for the passage of abrake-operating rod, (not shown,) and in one of the lianges of the plate9 are semicircular openings 17 for the same purpose, and over theseholes and openings ICO side of the bolster is secured to the bottomplate 24, whose width is equal to the width of the top plate 22 andterminates at the points 7 on the web just outside of the bearing-plates20.

The plate 22 is provided with an opening 25 and the plate 24 with anopening 26 for the passage of a king-bolt.

Having thus fully described-my invention what I claim is l. A bolstercomposed of a central web of fiat metal, provided with a bulge or swellin the longitudinal center thereof, and plates riveted to both sides ofthe web and forming lateral extensions.

2. A bolster composed of a central web of flat metal provided with abulge or swell in the longitudinal center thereof, and plates riveted toboth sides of the web at the top and the bottom and forming lateralextensions.

3. A bolster composed of a central Web of fiat metal bent laterally atthe longitudinal center thereof, tapering from a point near the centerbearing-plate beyond the end bearingplates, and plates conforming to theweb riveted to both sides of the web and forming lateral extensions.

4. A bolster composed of a central web of flat metal bent laterally atthe longitudinal center thereof, tapering from a point near the centerbearing-plate beyond the side bearingplates, and of the same width fromnear the side bearing-plates to the ends of the bolster, and having astraight upper or top edge, forming a cantaliver, and plates riveted toboth sides of the web at the top and bottom and forming lateralextensions.

5. A bolster composed of a central web of iiat metal bent laterally atthe longitudinal center thereof, plates secured to both sides thereof,and a top plate extending to and secured to the ends of the bolster.

6. A bolster having a central web of flat metal composed of two membersbent laterally and overlapping each other at the longitudinal center ofthe bolster, laterally-extending plates secured to the web, and a topplate extending the length of, down over and secured to the ends of thebolster.

7. A bolster composed of a central web of at metal bent laterally at thelongitudinal center thereof, laterally-extending plaies riveted to bothsides of the Web, a top plate extending the length of the bolster andriveted to said laterally-extending plates, and a bottom plate extendingbeyond the end bearingplates and riveted to the laterally-extendingplates.

8. A bolster composed of a web of flat metal deeper in the center thanat its ends and provided with a bulge or swell forming a kingboltpassage and a central lateral reinforce for the bolster,laterally-extending flanges secured to the sides of the web, a top plateand a bottom plate secured to said laterallyextending plates andprovided with openings for the king-bolt.

9. A bolster composed of a central web of lfiat metal provided with abulge or swell at its longitudinal center,laterallyextending platessecured to the web at its top and bottom, a top plate the length of thebolster, a bottom plate, center and side bearing-plates secured to saidbottom plate, and laterally-extending vertical braces over the sidebearings and secured to the web.

l0. A bolster having a central web of fiat metal of a single thicknessapproximately throughout its length, bent laterally and reinforced atits longitudinal center to form a king-bolt chamber or passage,laterally-extending plates riveted to the sides of the web, a top plate,and a bottom plate secured to the laterally-extending plates, and centerand side bearing-plates secured to the bottom plate.

In testimony whereof I affix my signature in presence of two witnesses.

JEAN A. THORSELL.
